METHOD OF AND MACHINE FOR MAKING' PAPER BOXES.

Application filed September 8,1924. Serial No. 736,564.

To all whom t may concer/1t.

Be it known that I, EMIL JAGENBERG, citizen of the German Republic, andresiding at Dusseldorf, Germany, have invented certain new and usefulImprovements in Methods of and Machines for Making Paper Boxes, of whichthe following is a specification.

My invention relates to improvements in the method of and machines formaking paper boxes, and the object of the improvements is to provide amachine in which a neck ring placed around a core is placed on a blankof card board supplied from a pile thereof, ywhereupon both parts areforced into a shaft for pressing and fixing the side portion of theblank to the gummed neck ring, the box members moving downwardly withinthe shaft and being dried therein, whereupon they are conveyed by aslide way into another shaft wherein they move upwardly for having thecores remoi ed therefrom.

F or the purpose of explaining the invention an example embodying thesame has been shown in the accompanying drawings in which the samereference characters have been used in all the views to indicatecorresponding parts. In said drawings,

Fig. 6, is `a perspective View vshowing a core, a neck ring and a blankassembled for being forced into the shaft, and

Fig. 7, is a similar view showing the blank with its side members gluedto the neck ring. f

In the example shown in the drawings my improved machine consists oftwoA yframe members secured to a base plate or foundation and having aplate or table 3 secured to their. top. To the table 3 a magazine 2 issecured which is adapted to receive a pile of blanks of card board 1 andto discharge the same at its bottom, a reciprocating slide 6 beingmounted below the magazine for successively taking therefrom the blanks.In front of the magazine aA pair of cleats 60 are securedto the table 3at opposite sides of a. hole 8O thereof, which provide a gui-de way forthe blanks taken from the magazine for guiding the same into positionabove a vertical shaft 7 mounted on the frame position corresponding tothe size of theV boxes by screws 68V and 41.

In front of the cleats 60 a plate 11 is secured to the table 3 by meansof screws 12, and at opposite sides of the said plate slides 13 and 14connected with each other by a crosspiece 38 are guided in guide ways 36and 37. To the slides 13 and 14 frames 15 and 16 are adjustably secured,and on the frame 16 a plate 17 is supported by means of bolts70 andsprings 69 permitting the plate 17 to yield towards and away from theframe 16. The frame composed of the parts 15, 16 and 17 isV adapted tohave a core 9 and a neck ring 8 placed thereon for carrying the sameinto position above the blank 1 located above the shaft '7.

Above the shaft 7 there is a plate or plunger 35 adapted to force thecore 9, the neck ring 8 and the blank 1 downwardly and into the shaft 7,and the said-plate or plunger depends from a cross-piece 81 secured to apair of rods 34 guided in suitable guide members 71 secured to or madeintegral with the table 3. At their bottom ends the said rods 34 areconnected to suitable gearing'adapted to impart thereto reciprocatingmovement.

At the top end of the shaft 7 means are provided for pressing the sideportions of the blank and the neck ring together and to produce sharpcorners. As shown said means consist of a pair of pressing plates 83 and84 mounted respectively on reciprocating rods 99 and 99 guided inbrackets 86 depending from the table 3. To the rear end `of the rods 99and the inner brackets 86 springs 105 are attached which tend to forcethe plate 83 inwardly and against the adjacent side portion of theblank, and the rods are` formed with collars 87 engaged by arms 88secured to a rock shaft 89. To the rock shaft f an arm 90 is securedwhich is connected with a suitable operating mechanism to be describedhereinafter. rlhe rods 99 are connected by a cross-piece 9S acted uponby an arm 97 of a rock shaft 96 connected by a` bevel gearing 95 withthe shaft 89, so that the plates 83 and 84 are sin'iultaneouslyreciprocated by the springs 105 and the operating mechanism as will bedescribed hereafter.

Later-ally of the shaft 7 a shaft 43 is mounted through which the boxesmoved downwardly through the shaft 7 are moved upwardly. Preferably thesaid shaft is equipped with cushioned and adjustable side walls similarin construction to the side walls of the shaft 7. rl`he boxes areconveyed to and lifted within the shaft 43 by means of a slide way 42rockingly mounted at 44 and extending from a point below the shaft 7 toa point below the shaft 43, and adapted to be rocked upwardly anddownwardly by means of a rocking lever I 46 secured to a rock shaft 45.

For operating the mechanisms so far described the following gearing isprovided. In suitable bearings a driving shaft is mounted which isadapted to be rotated from a shaft 49 carrying a pulley 46v through theintermediary of a pinion 50 and a gear wheel 51 loosely mounted on theshaft 25 and having its hub 57 formed with coupling jaws. On the outerend of the shaft 25 an arm is rockingly mounted which is acted upon by aspring 52 tending to force the same with a lug 72 into couplingengagement with the jaws of the hub 57. `Yormally the said arm isengaged by a beveled nose 54 made on a lever 55 holding the same awayfrom the said jaws. The lever 55 is keyed to a rock shaft 56 having afoot lever 24 mounted thereon. Then depressing the foot lever the nose54 is retracted away from the arm 53 which is therefore thrown intocoupling engagement with the jaws of the hub 57. There fore the shaft 25is rotated. Then releasing the foot lever 24 the lever 55 gets into thepath of the arm 53 and rocks the same out of engagement with the jawsfor interrupting the rotation of the shaft 25.

To the shaft 25 a disk 23 is keyed which is formed at its end face witha cam groove 73 engaged by a roller 74 of a lever 22 jointed to an arm75 keyed to a rock shaft 76. rlwo arms 21 of the latter are connected bylinks 2O with the slides 13 and 14 for imparting reciprocating` movementthereto. fr crank arm 26 secured to the shaft 25 is connected by a link27 with a crank arm 28 of a rock shaft 29 having a bell crank lever 31secured thereto. One arm of the said lever is connected by a link with alever 5 secured to the rock shaft and connected by a link 4 with theslide 6.

The other arm of the bell crank lever is connected by a link 33 with across-piece 78 carrying the rods 34 and 35. To the shaft 29 an arm. 700is keyed which carries a weight SO.

rl`he shaft 25 carries a cam disk 94 engaged by a roller 93 of a rod 91guided with its slotted bottom end 92 on the shaft 25 and jointed to thearm 90.

To the shaft 45 the lever 46 is secured which is therefore; rockedupwardly and downwardly by the lever 5.

For operation of the machine by hand a lever 29 carrying a handle 59 issecuredl to the shaft 29, as is shown in Fig. 2 inA dotted lines.

The operation of the machine is as follows:

1n the position of the parts shown in Figs. 1 to 3 a blank 1 has beenplaced by the slide 6 into position above the shaft 7, and the slide isabout to be retracted away from the blank. The plunger or plate 35 hasbeen lifted into its uppermost position, and the slide 13 to 17 is inthe position in front of the shaft 7 and the hole 80.

A neck ring 8 having glue applied to its outer face is placed by hand ona core 9, the joint 10 of the ring being located at the middle of one ofthe longitudinal sides, and the block 9 and the neck ring 8l ar placedon the plate 11 andy into the frame 15, 16, 17 with the neck ringbearing on.

lugs 18 and 19 of the frame 15, 16 so that it is held on the core inclosed position. Now the clutch 53, 57 of the driving shaft 25 is throwninto coupling position by means of the foot lever 24, so that the shaft25, the cam disk 23 and the crank arm 26 keyed thereto perform onerotation. By the first part of the rotation the roller 74 is engaged bya portion a ofthe cam groove so that it is forced upwardly, and the arm21 is rocked to the right, thus carrying along the slide 13 to 17 andthe core 9 and the neck ring 8 placed thereon. The core and ring `getinto position above the blank 1 and the shaft 7 and they are held inthis position by the roller 74 riding in a concentric part of the camgroove 73 provided between the point a# and a point b. During this partof the rotation of the shaft 25 the crank arm 26 rocks the shaft 29 inanti-clockwise direction. Thereby the slide 6 is retracted from theblank 1 and into position at the rear of the pile of blanks 1, and theplate 35 is moved downward.

ly and into engagement with the core 9 located above the shaft, whichcore is thus forced downwardly and into the shaft 7, the side members orwings ln of the blank being bent upwardly and against the gummed neckring 8. The core and box are held within the shaft by friction and theyforce the lowermost one of the cores and llO boxes previously made outof the shaft and on the slide way 42. After the shaft 25 has beenrotated through 180o the plate is moved upwardly and the slide 6 beginsits forward stroke for shifting another blank 1 into position above theshaft 7. Shortly thereafter the rollerv 74 is engaged by the part of thecam groove and thereafter by the portion of smaller radius, whereby theslide 13 to 17 is again shifted forwardly or to the left in Fig. 1 forreceiving another' core 9 and neck ring 8. After the plate 35 hasbeenlifted the cam disk 94: is moved so as to permit the springs 105 topress the plates 83 and 84 against the blanks, neck rings and coreslocated iu the upper part of the shaft for bending the corners of theblank into sharp form.

By thus repeating the operation of the machine the finished boxesgradually move downwardly within the shaft 7 and there is plenty of timefor drying the gum. The boxes and cores which are successively pushedout of the shaft 7 fall on the inclined slide. way i-2 and they slidethereon into position within the bottom part of the shaft e3. Duringeach operation of the machine the slide way 42 is once rocked upwardlyby the lever i6 for lifting a box and core placed thereon into the shaft43, thus lifting the boxes piled up within the shaft. Iflhen arriving atthe top ofthe shaft the boxes are removed by the attendant, and thecores are taken out of the same for being used again. Within the shafti3 the boxes are held by spring pressed pawls 47.

For removing the finished boxes from the cores a suitable apparatus ismounted on a side portion 102 of the table 3. To the said portion a pairof spaced bars 103 are adjustably secured by means of angles 10d, thedistance of the bars being such as to permit the cores and the boxes tobe placed between the same. The upper parts of the bars project slightlyinwardly and above the top edges of the boxes for holding` the. same inposition when removing the cores. After removing the core the box isremoved from the bars by means of a new box and core pushed between thesame.
